    Hello Members,is there info out there as to where to buy brake shoes and linings for the front 101 brake drum?  Or what other model of motorcycle will fit and being used. I've looked thru our forum and Walker Machine, but did not see any info or parts.Thanks again for your time.

    741 shoes are pretty much the same, it's either that or have them relined .

    Used to be able to pick up NOS 741 shoes fairly easily.

    Let us know if you find a good source.

    Walker machine parts is here: http://walkermachine.com/frontwheelbrakegroup.aspx

    From what I can see on the page, Walker doesn't supply readymade brake shoes, but material for relining. Here's a picture on how rivets should look properly done:

    And a example of tool for that:

    CWS moto has a lot of brake parts and possibly brake shoes if you ask.

    I found pictures on the Reno site. He doesn't update price or availability on his site, so you have to mail and ask.

    -------------A note regarding the many times excellent repro parts available nowadays. New is good in many cases. Just a little wear (rounding off) of the brake cam both (already round) outer edges diminish the brake efficiency substantially, and wear trenches in the shoe surface where the cam wedge against is lessening the force that the cam can and should exert against the shoes, so that is important areas to look into (fill in and ground flat). Brake cam bushing wear in the shield should not be allowed as it makes the cam tilt. Wear in all those areas together with flex in the brake cable makes the brake spongy and travel range at the handlebar lever too short.-------------------------

    Some advocate use regular aluminium pop rivets, I strongly advise against that because the rivet material is soft, hollow through, thin and the clamping force is unknown for various quality pop rivets! Add to that a small ball of steel that is remaining in the rivet that needs to be secured or removed.

    If you want to know more about brake friction materials that should be used for our light weight motorcycles, ask various professionals.

    Glue bond the material is well known and safe way if done proper. Some friction materials is only suitable for bonding. If I choose that method I would have a professional shop do that in an oven.

    P.s. I agree with Ken, rivet a lining even if it is bonded.

    I advise always to use rivets even though professionally bonded !! I rode 230 miles home with just rear brake on my KJ after professionally bonded shoes came off front brake . I know others who's bonded shoes have come off so even IF I have them bonded I recommend riveting as well , even if just on the trailing part of the shoe . belt and braces job !!! Ken

    Thanks everybody for fast input,tips, & knowledge. I will check the 741's & Reno as I need both, the brake shoes and linings. Also I will have rivets installed by pro Clutch and Brake shop as a safety net with or without bonding. I'll let you know what I find and use.

    I had rear shoes that needed linings on my 1931 scout rear wheel.The pro Arizona clutch & brake shop that has been around for many decades will not do any motorcycles any more. But they referred me to P&O Brake in Las Vegas that does new & antique cars and motorcycles.I sent my shoes to them & 2 day turn around had new linings bonded plus rivets countersunk installed.$47 each [+ shipping,$7.50]Great communication with these guys. I also bought my front wheel 741 shoes with linings that were NOS from Bobs Indian Sales. All parts fit great and quickly on to other 101 issues. Thanks again

    I am ready to re-line my brakes with friction material from Randy Walker.  I have a couple of questions I'm hoping you can help with (and thanks to all who have contributed to this thread - it was very informative.

    1.  The friction material for my front brakes is longer than what I removed.  The new material will hang-over the surface of the shoe by 3/16" on each end if centered as shown in the photo.  Should I trim the material to be flush with the shoe?

    2.  The friction material for my rear brake is shorter than what I removed.  The old material came to within 1/8" of the threaded rod attachment.  The new material is 1" shorter.  You can see in the photo that there is an old scribe mark where the material ends, so is this the correct alignment?

    3.  The front material is 4mm thick, the rear is 5mm thick.  How deep should I countersink the rivets?

    Thanks for sharing your expertise.

    John

    Important is that the leading edge of both front and rear brake linings gets a fairly long chamfer (slant cut), that prevents the lining from grab and chatter! The rear edge can be cut square.

    1,5mm should be enough remaining material when you countersink.

    For the front brake lining, shorten it so it does not overhang unsupported. 

    For the rear brake, 1" shorter lining than what was there before, I would call Walkers to hear what reason he has for that. In a pinch move the short one or both linings further up against turning direction, that would give better braking effect, the brakes are poor from the start. Better call or write Walkers for advice.

    Remember to adjust the rear brake bands individually. Applying the brake pedal a little, when the upper band is firm against the drum, the lower band should be possible to wiggle a little sideways with your hand. That is because the lower band is leading band and is gripping harder. Applying a little more pressure on the brake pedal the lower band should become firm.

    Important!! When finished Be sure to check with a feeler gauge that the band is clearing the drum all around. If not then reshape the band or glue a thin sandpaper around d the drum and careful sand only just enough.

    After a while when the linings are run in, it is very important to readjust the bands carefully the same way again.

    Brakes are important and knowledge on how it works is essential for getting best effect and avoid dangerous failures. External brake band and internal shoe brake is working the same, in regard of leading and trailing lining. 

    One danger is that if adjusted wrong the brake can pinch and lock the wheel if and when the drum heats up! Be sure to check with a feeler gauge that the band is clearing the drum all around. If not then reshape the band or glue a thin sandpaper around the drum and careful sand just enough.

    I surely don't know all but here is some illustrations and pictures to explain better what I am trying to describe.
